Answer #1

POST TRANSLATIONAL MODIFICATIONS ARE MODIFICATIONS OF PROTEINS FOLLOWING PROTEIN SYNTHESIS. PROTEINS ARE CHAIN OF AMINOACIDS JOINED BY POLYPEPTIDE BONDS. PROTEINS ARE SYNTHESISED BY TRANSLATING MESSENGER RNA IN THE CYTOSOL OF THE CELL BY RIBOSOMES.

POST TRANSLATIONAL MODIFICATIONS REFERS TO CHEMICAL CHANGES A PROTEIN UNDERGO AFTER TRANSLATION. THESE CHANGES HELP THE PROTEIN TO DO SPECIFIC FUNCTIONS IN THE BODY. FOR EXAMPLE POSTTRANSLATIONAL MODIFICATIONS PLAY AN IMPORTANT ROLE IN REGULATING THE FOLDING OF PROTEINS , REGULATE THE INERACTION OF PROTEINS WITH OTHER PROTEINS , REGULATE THE FUNCTIONAL STATE OF THE PROTEINS SUCH AS ITS CATALYTIC ACTIVITY IN THE CASE OF ENZYMES , REGULATES THE SIGNALLING FUNCTION OF PROTEINS. ETC.

EXAMPLES OF POST TRANSLATIONAL MODIFICATIONS ARE PHOSPHORYLATION , AMIDATION , DEAMIDATION , ACETYLATION , METHYLATION , OXIDATION , HYDROXYLATION , AND FORMYLATION

Glycosylation describes a whole class of post-translational modifications that are found on many types of proteins, in which one or more carbohydrate monomers are covalently attached to the surface of a protein by enzymes that have evolved to add these modifications. Such proteins have evolved such that they function best when glycosylated. When cells are exposed to high levels of glucose, however, many proteins may react with glucose (without specific enzymes as catalysts) to form “advanced glycation end products.” These...
